# Cyclus vs Longevity Protocol

The clearest difference is ads: Longevity Protocol at none against Cyclus's shown. Longevity Protocol also leads on update cadence (every 5 days vs every 4 weeks) and device support (3 vs 1). Cyclus's advantage is iOS requirement (17.6 vs 26.0). On price and in-app purchases there is nothing between them.

Both are free to download. Cyclus sells 2 in-app purchases, starting at $9.99 per 7 days and Longevity Protocol sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Cyclus ships an update every 4 weeks, Longevity Protocol every 5 days. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
